Abstract
In pear tree, Forficula auricularia and Forficula pubescens are considered as active predators of the pest Cacopsylla pyri, since that their dispersal characteristics are of crucial importance for biological control. We studied their movement using capture-mark-release-recapture techniques. The aim of this study was to underline a hedge effect as source of beneficials spreading through the orchard. Our results show that movements are mainly linked to the C. pyri fluctuations with a food specialisation for the two species when co-occurring.
